Reuben Hersh, a mathematician and mathematics philosopher, believes humans created math. He reasons that math is all in the heads of humans, and is a “social phenomenon”. According to Hersh math is not “physical, not mental, but social”. Math to Hersh is a creation of humans that would not be found in other regions of the universe. According to Hersh if there were other life forms out there in the universe they would not have the same math that we have. Hersh agrees that there could very well be aliens out there in the universe who use mathematics, but he feels that their math would much different than ours.
